At 2:46 pm local time March 11, an 8.9-magnitude earthquake struck Sendai, a port city of one million residents in northeastern Japan. It was the largest earthquake recorded in Japan in the last century.

On March 11, a powerful, 8.9-magnitude quake hit northeast Japan, triggering a tsunami with 10-meter-high waves that reached the U.S. West Coast.

At 2:46 P.M. Tokyo time, one of the largest earthquakes of the past century hit just off the coast of Honshu, the main island of Japan. The 8.9-magnitude quake stirred up massive tsunami waves that battered coastal cities, especially along the east coast north of Tokyo.

The 8.9 magnitude earthquake in Japan is causing problems for at least one of its fleet of nuclear reactors--and authorities have shut down 10 of the country's 55 units.

Much of this has to do with the depth of the ocean that the tsunamis waves traversed as well as the sheer size of the quake, which was the strongest recorded in Japan's history

Our partners at Nature have a correspondent in Japan.

This post is a slightly edited version of my December 29, 2004, post written in reaction to media reports about a "sixth sense" in animals, that supposedly allows them to avoid a tsunami by climbing to higher ground.

Will seismologists ever be able to reliably predict the exact location, time and magnitude of earthquakes like the one that just devastated Japan and sent tsunamis racing across the Pacific Ocean? If so, they might be able to save many lives.

Like many Americans, I have recently been diagnosed with a vitamin D deficiency. In addition to drinking milk, eating dark leafy greens, and taking 2000 IU’s of D a day, I’ve also been trying to get as much sunlight as possible. When I came across this article in the November 7, 1903 Scientific American , I realized that a possible reason for my deficiency is my home’s inability to rotate

Elephants are smart, social animals. And now we know that they can organize themselves into teams to accomplish tasks. A research team that included renowned primatologist Franz de Waal taught 12 Thai elephants--who already work with human trainers called mahouts--to get a bowl of food by pulling a rope attached to an out-of-reach table

Climate change will pose major new hurdles for U.S. naval forces, forcing the military to grapple with an emerging Arctic frontier, increasing demand for humanitarian aid and creating rising seas that could threaten low-lying bases, the National Academy of Sciences said yesterday. "Even the most moderate current trends in climate, if continued, will present new national security challenges for the the U.S.
